Mark Ballas' Audi was involved in a three-car fender bender on the Sunset Strip that left the vehicle so damaged it couldn't be driven - and the Dancing With The Stars dancer wasn't even behind the wheel!

Apparently, his girlfriend Tiffany Dunn was responsible for the crash when she drove into a Porsche, which in return, knocked that car into another!

Luckily, no one was hurt and insurance can cover all of the damage, but eek!

We imagine this means he'll be suspending Miz Dunn's driving privileges for quite some time!
